The results show that the dissolution process of prefabricating alloy can be divided into two periods when the temperature of zinc melt is below the melting point of aluminum.Firstly,zinc melts infiltrates into the prefabricating alloy and then Zn-Al-TiC alloy forms in the surface layer of the prefabricating alloy.Secondly,the Zn-Al-TiC alloy of this alloy surface layer begins to dissolve to the zinc melt.

结果表明：当锌熔体温度低于铝熔点时，预制合金的溶解可分为两个阶段：第一阶段为液态锌向预制合金中浸渗，并在预制合金表层内形成Zn-Al-TiC合金；第二阶段为预制合金表层内的Zn-Al-TiC合金开始溶解并进入锌熔体。

Process and mechanism of electrodeposited Zn-Fe-Si02 composite coatings were studied, including some contents as follow: Potential-pH plots of Zn-H2O and Fe-H2O systems were drawn, and the thermomechanical analysis was made. Results showed that the region of zinc and iron's codeposition was wide, which provided theoretic basis for electrodepositing Zn-Fe alloy. But the balance potential of zinc was greatly different from iron's, so in order to make zinc and iron codepositing, some complexant must be added into electroplating solution.

本文研究了电沉积Zn-Fe-SiO_2复合镀层的工艺和机理，主要包括以下几个方面：绘制了Zn-H-2O系和Pe-H_2O系的电位-pH图，并对其进行了热力学分析，结果表明，锌和铁发生共沉积的区域很大，这就对电沉积Zn-Fe合金的可能性提供了理论依据，但是锌和铁的平衡电位差别较大，所以，必须在镀液中添入一定量的配合剂才能使锌铁产生共沉积。
